w a w@ @New MQ pinion 6 is mounted on the rotary sleeve 9,' fps alsoy isthe ratchetv wheel 10g which, when y the paper carriage is drawn "tothe'left by the spring'drive, is coupled by the pawl 12,

' under vaction of the spring 11, (Eig. 7) with the toothed wheel Smounted. on the salme axle. The toothed wheel 8 engages a pinion 13,Fig. 7on the spindleot' which ismounted a beveled wheel 15 in gear withthe bevel wheel 14:1 (Fig. 1). The spindle of 14 carries the crank 16(Figs. 1 and 9) A and the double ended arm 17 (Figs. 1 and 11), the

v ends of which are bent as at 17a, 117). The

bend 1'?a lies nearer the .axis than the h'ook 17". These'hooked endsform with thepawl 18, mounted on the shaft 19 and'under the iniuence ofthe spring 20, an alternate locking for the driving mechanism. .Thecrank 16 is connected with the lever arm 22, which in its turn 1sconnected with the main shaft 23 in a manner presently to be described.Y On this main shaft 23 is fixed a projection 25 carrying a. tube 24(Figs. 1 and 2). On the tube 24- (Fig. 2) is the type roller 26 mountedto turn and slideaxially thereon. Inthe projection 25 and the closed-endof the tube 2l is journaled the shaft 27, which carries the rollershaped hammer head 28. Over this and the tube 2l is pushed the tyi'ieroller. The hammer head is turned oution one 'face and in the recessthus formed is riveted the end 29a Aor' the spring 29 (Figs. 2 and 5)the f other end 29b is bent and passes through-the wall of the recessand through aslot in the Wall of the type roller situated between twocolumns of type. The type roller is in this I manner movedwith the'hammer head when this is turned, but at the saine time may be shiftedlongitudinally. The type roller has lat the other end a closing ring`3() and at the hammer end a cover 31. On the shait27 is mounted abevelwheel 32 (Figs. 1 and 2.)

i' lllfloreover there 1s journaled on the shaft a .ldrawn to an enlargedscale.

hollow sha'ft`33 (Fig. 2) which is provided with a screw thread. In alongitudinal slot ,of the tube 24 there isf a small slide 34; thespringt-l5 fixed bya screw to this slide is bent over the closing ring30. The slide has .at its inner side a projection with a groovel 36 inwhich Ythe screwed thread of the shat't 33 engages. In Fig. 10 the slideis shown When the shaft 33 is turned the slide is moved and with it thetype roller. v Shaft 33 is rotated by means of the bevel wheel 37mounted on it.

journaled on the shaft 19 and are pressed by springs 39,V Fig. 3,against stops 40. Keysy by the rod 21 (Figs. 1 and The levers E; to Rt(Figs. 1l and 3) are may be pressed by similar springs against stopslike those shown in F ig. 3 for keys R lto R4. The keys are shown inFig. 1 in them through pins 11 (Figs. 1 and 3) the shaft 19 andtherewith the pawl 18 when they are depressed. ln this manner the end17a of the arm 17 is unlocked (Figs. 1 and 11) whereupon the crankperforms half a revolution and the typev cylinder is struck against thepaper roller However, before the type cylinder comes in contact with thepaper roller, the pawl 18 engages the other end 17b of the arm 17. Inthis mannen the paper carriage is brought to rest. The lever 22 isadapted to turn on the journal 43 (Figs.` 1 and 9) otthe shaft 23. Thedisk {ll mounted'onlthe latter has a pin 15 which lies in a recess ofthe lever 22, which therefore has a small pla y. The spring 46 pressesthe lever against the pin This device permits the type roller, inconsequence of its momentum, to strike the paper when the carriage is atrest and' lifts the roller from thepaper again. V'Vhen the keys RL-R'*return to the position of rest the second end 17 of arm 17- is liberatedI' treme right hand sleeve 47 is'fiXed to the shaft 23, the rest arerotatable thereon.

The extreme left sleeve 47 carriesthe 1nevel vwheel 48 which enga ges,the bevel'wheel 32 (Figs. 1 and 2) mounted on ,the shaft 27.'

0n the sleeves are riveted disks 19a-49' and- Furthermore rings 51?* to51d are. threaded on the sleev/es and in these rings f are riveted flatsprings 52-52". Disks 19a-19d have slots 53 (Fig. S)- which serve forguiding the springs 52. The disks 50aw50d have slots4 (Fig. 3) intowhich springs 52 exten'd/ These slots have at their 'upper partsseparate recesses into which the springs enter. In/. this position ofthe springs 'the sleeves are coupled together.

lf, however, the springs are depressed out of these recesses into thelarger/portions of the slots by pressure of the keys R-R* through theintermediary of the projections 1' (Fig. 3), the sleeves may be rotatedrelatively to each other through an angle corresponding with the siseolf-the slots.

Tigh; angles R and L may be actuated directly by the fingers, so 'that asingle key or a combination of' keys may correspond with the separatetypes. This would be theideal key board, because each finger wouldremain resting on its key andthe choice of the keys is merelya"`question of brain work without the assistance of the eyes. Ashowever, the operation ot this key board may appear too difficult. thereis shown in Fig. 13 an arrangement of keys which approximates to theideal Without deviating too far from the usual key board. i

The frame levers 601 to 60M are journaled on the shafts 19 and 38, eachof which levers carries a key.. F ig. 14 shows one of these frame"levers with its key in perspective. The levers R and L rotate or shiftaxially the type roller to an extent corresponding with their indexnumber. The keys T 1 to T1n the coupling gear,

bring the irst ten types into the printing position since they areprovided with co1 responding projections 60a for the .levers R or forthe'necessary combination of levers. The key T11 moves the lever L1, thekeyv T12 moves the lever" L2. With these twelve keys the thirtycharacters of the first, second and third rou1 of type may be broughtinto position. For the types numbers l1 to 20 the additional key T andfor the types numbers 2]. to 80 the additional key T12 is simultaneouslydepressed with the cor esponding key T1 to T1". The key Tlamoves thelever'lf, the key T14 moves the lever L", and the key ZW directs thespace shifting. The types may be arranged in the usual manner and thecharacters may` be inscribed on the keys. There are however, by thisarrangement additional keys T and T12 substituted for twenty keys andthe fingers can almost -always rem in resting on their keys. The keys T,"Wand ZW are depressed b v ther-thumbs. the rest of the fingers remainalways on the main row of keveu one plane as their strokes needamountionly to 2 to-S millimeters, compare Fig. 15. This short stroke isonly obtainable bv the automatic positioning of the type roller and theautomatic imprinting' of the t/vpes's/o that .this simplifiedarrangement of keys is not dependent merely on the construction 'ot theshift keys as additional kevs to oth/er additional keys and to thcvmainkeys, but on this automatic operation of the machine. With longerstrokes the main keys can not be depressed by themselves withoutinvolvingan uncomfortable position ofthe fingers which would hinder'rapid Writing as will be apparent from Fig. 15... l

lt is obvious that by increasing the numl ber of levers 60, the numberof kevs may be increased, e.. the keys T a'nd Tfhiav l( each be replacedby ten indiyidual keys.'y It.'

se will also be understood/that ter 'unlocking' Tl--Tl All the-keys mayhe arranged iniA the Wheel 65 is journaled on atubular prolevers in `theform of frames may be used and such frame levers may be selected bylevers in the form of y key levers. The employment ot a second systemcllevers to ai'iton'iatically select the keys provided with the propel'characters permits of any desired arrangement of the ke s.

il very advantageous and modified form of type roller withv remarkablysmall dimensions, is produced by composing it of several small typecylinders rotatable about a common center and arranged in a circle, thevarious characters being yarranged. on these rollers in annular zonesand-longitudinal divisions. The character l to be imprinted -is thusbrought into position by rotating and axially shifting the compoundtyperoller.- and also by rotating the'individual type rollers. Figs. 16 to20 show such a modification or' the type-wheel andthe operating meanstherefor.

Fig. 16 shows the whole `arrangement in front elevation. Fig. 17 showsthe arrangement for shifting the whole of the type rollers 'as-seen fromthe left; Fig. 18 shows the type roller in plan; Fig'. 19 shows thetoothed segments which serve for rotating the whole type cylinder andthe individual rollers, seen troni the right; Fig. 2O shows the sepa- 95rateparts of the shifting device for positioning the type. rollers.

On the horizontal main shaft 23, journaled in front of thc papercarriage is mounted the carrier 25 in which the pin (il is mounted` soas to slide. On this pin' a bobbin 62 can rotate but is prevented fromshifting by a Wire clamp. In lthe end plate of this bobbin are journaledten driving wheels 63 only'tivo ot' which are shown in F ig. 16, one in,elevation and one in section. Between the end plates, sleeves 64 aremount/ed on the shafts driven by wheels 10 and 'rotate with the shaftby'friction. Each of' these sleeves carries on its periphery nine typesin three annular Zones, and three longitudinal divisions separated fromeach other by angles .ot 120. ln one of these diyisions three smallcharacters are arranged, 1n the second correspondingxlarge charactersare arranged, and in the third certain numbers and signs are arranged.For driving the whole of these ten small type rollers the spur wheel 65engages with the Wheel 63,-

Ajection of the bobbin 62 and'is heid in position by a ring sprungthereon. ln a certain vposition of this spur `wheel there are on theouter side of the b'obbin thirty small lcharacters/for which aresubstituted. by turning the individual rollers through 120"7 the corresponding large characters and by a 'fui'- ther 'rotation through 120the numbers and signs. yThe characters may be so arranged that ,thesmall cliaractersare in.y the upper in he lower'zone.
